Anyone else use them?
I have taken the CVS brand. (Not TTC right now just checking to see if I am Oing)
All the ones I have taken only have the control line. NO sign of a test line what so ever...
Is that normal?

i used $tree brand and found that there was barely a line, if at all, when i wasn't close to O...then a day or so before i'd get a pos. there would be a light line, but when it was pos it was pos for sure.
